What it is

The Reznor 36 25212 is a hot surface ignition device with a carborundum element, used to light the burner on Reznor ML and UL series heaters. It forms part of the ignition circuit, heating to glow point so that gas is ignited at the burner when there is a call for heat. The manufacturer designates this device for both UL and ML appliance families, covering room sealed and open flued ranges.

Signs this part needs replacing

  • The burner fails to light on a call for heat and the appliance locks out.
  • The ignition device does not glow during the ignition sequence.
  • Visible cracks, crazing or physical damage to the carborundum element.
  • Repeated lockouts after reset, with gas present at the burner.
  • The ignition sequence runs but no flame is established.

Before you order

  • Confirm the appliance model against the fitment list for this device.
  • Inspect the existing ignition device for physical damage before ordering.
  • Isolate the electrical supply and the gas supply before removal.
  • Cross-reference the alternative part number 3625212 if working from older documentation.
